As of this writing, the site has been down more than four hours, which is an unusually long time for a robust agency to recover from a DDoS attack. That raises the possibility that the site remains down for some other reason. It could be some other kind of penetrating operation, which you could call a hack. Or it could yet have been a DDoS assault, and the CIA may be keeping the site down while it investigates and scrubs it for security holes. Not a hack.

As the federal government tells it, the money men behind the Sept. 11, 2001, hijackers would never have been identified had they not been lousy bankers:

“The 9/11 hijackers opened U.S. bank accounts, had face-to-face dealings with bank employees, signed signature cards and received wire transfers, all of which left financial footprints. Law enforcement was able to follow the trail, identify the hijackers and trace them back to their terror cells and confederates abroad.”

That’s from a Treasury Department assessment of financial security threats in 2005. It went on to warn that the terrorists could have quietly moved large sums of money into or out of the U.S.:

“Had the 9/11 terrorists used prepaid … cards to cover their expenses, none of these financial footprints would have been available.”
